You know, this one sentence betrays every ounce of insecurity Caroline Forbes has. And the fact that Klaus constantly asks her whether or not she wants the cure - at the back of her mind - makes her feel wanted, like somebody actually thinks about her at least once a day. Even Elena and Stefan, they called her only because they needed help. They didn’t ask her if she wanted to come along, whether she wanted the cure - they only wanted her help. Tyler or Matt could help them out - why Caroline?

This is why I ship Klaroline. Because it brings out the insecurities in both those characters, and the other indirectly or directly helps them.
